JWhen it comes to virtualisation, you want RAM (the more the better). When it comes to Proxmox, you want enterprise SSDs. You didn't list what drives you're planning to get. I suggest you research both these points.

Jjdancer replied to the thread Dell PERC H755 firmware fatal error and controller reset after single SSD failure — Proxmox/Ceph node-wide I/O hang.Always considered best practice to have OS and data/VMs on separate drives. Can use same controller. For example, I use two small drives to ZFS RAID-1 Promxox and rest of drives for OSDs. As for the controllers, the drama with Dell PERC RAID...

Jjdancer replied to the thread Upgrading single-node PVE 8.3.3 to 9: any gotchas with LXC containers?.When PVE 8 was going EOL in one-week, I backed up the /etc directory and existing LXCs (don't run any VMs) via the native backup functionality. Did a clean install of PVE 9 and restored the LXCs. LXCs came up with no issues. I didn't do an...

Jjdancer replied to the thread Clarification on ZFS Encryption at Rest – Proxmox VE 9.2.3.I had a use case to mounting a non-boot/root encrypted ZFS pool. This was for a bare-metal Ubuntu machine. As you know, Proxmox is Debian with an Ubuntu kernel. Called this systemd unit file "late-zfs-mount.service". I made sure it was the very...

Jjdancer replied to the thread [SOLVED] Dell PowerEdge R630 reboots immediately on kernel 6.17.2-2-pve (PWR2262 / CPU0704 / UEFI0078).None. These are headless Proxmox Ceph cluster nodes at work. Workloads are Linux VMs. I am guessing passing through a discrete GPU is another set of problems. At home, I have a Supermicro 1U server with a Intel CPU with integrated Quicksync. It...

Jjdancer replied to the thread [SOLVED] Dell PowerEdge R630 reboots immediately on kernel 6.17.2-2-pve (PWR2262 / CPU0704 / UEFI0078).I am guessing you are running the latest BIOS and firmware for the R630. Using E5-2650L v4 without issue in production. Yes, I do have I/OAT DMA and X2APIC enabled. Do NOT have SR-IOV enabled because don't need it. Don't know if matters, I use...

Jjdancer replied to the thread recommended 100 Gbit/s NICs for Ceph.So far, E810 issues have been resolved at work. As with all things, one must do their own due diligence and test their own infrastructure. YMMV.

Jjdancer replied to the thread Kernel 7.0.14-14-pve: immediate reset + CPU machine check when igb loads on I350 (Dell XC730xd) — 6.14 unaffected.I don't enable SR-IOV on the 13th-gen Dells at work in production. Running without issues. I do enable X2APIC and I/OAT DMA though. All servers are running latest firmware (BIOS, NIC, iDRAC, etc, etc).

Jjdancer replied to the thread recommended 100 Gbit/s NICs for Ceph.At work, the order of precedence for reliability is: 1) Mellanox (CX-6) 2) Intel (E810) 3) Broadcom (NetXtreme/Thor)

Jjdancer replied to the thread losing dirty-bitmaps during Live Migration.Probably a long shot but the only clusters I manage at work are Ceph. Not ZFS. For testing, try setting the VM cache to none/default (obviously reboot the VM). YMMV.
-
Jjdancer replied to the thread Live Migrations get slower over time.I found out through trial-and-error live migrations with Ceph, I had to set the VM cache to none/default. Started doing this way back with Proxmox 6. Today's AI bots confirm this is correct setting for Proxmox Ceph live migrations. YMMV. I don't...

Jjdancer replied to the thread H330 sas controller failed after upgrading to Kernel 6.17.2-2-pve.LOL, as I mentioned before, to avoid megaraid_sas driver drama, get a Dell HBA330 (which are cheap to get and uses the LSI3008 chip) which is a true IT/HBA-mode controller. Flash with latest Dell firmware. It uses the much simpler mpt3sas...

Jjdancer replied to the thread Do you think we can install Proxmox into a Dell E660 vxrail server?.Since the base reference PowerEdge server for the E660 is the R650, it should work. I suggest you "de-brand" it to a standard R650. That requires flashing the PowerEdge Identify Module, factory reset the iDRAC, then flash the R650 BIOS, iDRAC...

Jjdancer replied to the thread rhel initrd getting corrupted during import.Missing the the '-N/--no-hostonly' option for dracut which loads all drivers for initrd. This is my procedure way back migrating from ESXi to Proxmox...

Jjdancer replied to the thread HPE DL380 GEN9.Need to be more specific on installation issues. I have successfully installed Proxmox 9 on Dell PowerEdge R730s (all R730s are updated with latest firmware) which is equivalent to a HPE DL380 GEN9. I did have to enable X2APIC and I/OAT DMA in...

Jjdancer replied to the thread Upgrade 8 to 9 on HP DL360 G7.Just did a clean install of my Supermicro home rack server from PVE8 to PVE9. Yeah, I wait until the last minute. No worries, I've been clean installing PVE9 at work on Dell servers since PVE9 came out. Prefer clean installs. Got punked too many...

Jjdancer replied to the thread Dell PowerEdge R640 compatibility.Been running latest version of Proxmox on Dell 10/11/12/13/14/15-gen servers without issues. These servers were previously running VMware. Just make sure to run the latest firmware (NIC, BIOS, disk controller, iDRAC, etc, etc). If going to use...

Jjdancer replied to the thread CEPH Performance.As they say, it depends on workloads. Ceph is a scale-out solution, more nodes/OSDs = more IOPS. At least you got the right number of nodes and networking correct at the beginning. Been using Ceph Tentacle erasure-coding for some VMs workloads...
